Remember, a+b+c=180
3x+x+60=180
subtract 180 from 60
make that 3x+x=120
combine like terms
make that 4x=120
x=30
Triangle is Isoceles Acute Triangle
Let me know if you need anymore help.
Good Luck

x = 30, and the triangle is scalene because none of its angles are equal. To get this answer first subtract 60 from 180, because all 3 of a triangle's angles must add to equal 180, and we know one is 60 degrees.
180 - 60 = 120
Now we know 3x and x must equal 120, so the best thing to do know is combine them and divide 120 by 4.
4x = 120
x = 30
